  • Patent number: 5083961
    Abstract: In a bag flying-out toy, a foaming material including a plurality of foaming agents which generate gas at mixing thereof is accommodated in a gas-tight bag toy unit. An accommodating bag unit has its volume at swelling thereof, which is smaller than that of the bag toy unit at swelling thereof. The bag toy unit before swelling thereof is accommodated in a folded manner in the accommodating bag unit. The accommodating bag unit is ruptured at a swelling pressure of the bag toy unit due to the foaming material. Alternatively, the bag toy unit before swelling rests on a substrate. A tearing cover is provided for covering the bag toy unit on the substrate to fixedly mount the bag toy unit to the substrate. The tearing cover is torn off by a swelling pressure of the bag toy unit.

  • Patent number: 4758198
    Abstract: A gas-inflatable bladder toy is disclosed, in which a plurality of films are stacked with their peripheral edges being sealed for forming a bladder to be inflated by filling a required pressure gas therein, said bladder being adapted to be fed with an external gas and provided with an air valve in a flat double cylindrical form for checking an internal gas, or alternatively in which the same construction of the bladder contains a plurality of receiving bags separately receiving certain foaming agents which are chemically reacted upon mixing to produce a gas, these filling bags being broken by an external force. In accordance with the gas-inflatable bladder toy of the invention, the shape of the receiving body containing the preexpanded bladder 1 may be quite different from the shape of the expanded bladder 1 after opening the receiving body 7 and expanding to the given shape, thereby to provide an exciting bladder toy with a surprising effect.
